1.
 for (int i =0; i<GlobalCategoryPanel.Controls.Count;i++)//GlobalCategoryPanel是个Panel控件
            {
                if(GlobalCategoryPanel.Controls[i] is AdvancedPanel)//AdvancedPanel是个自定义控件
                {
                    AdvancedPanel ap=(AdvancedPanel)GlobalCategoryPanel.Controls[i];
                    for(int ap_i=0;ap_i<ap.Controls.Count;ap_i++)
                    {
                        if(ap.Controls[ap_i] is Panel)
                        {
                            Panel ap_panel=(Panel)ap.Controls[ap_i];
                            for(int ap_panel_i=0;ap_panel_i<ap_panel.Controls.Count;ap_panel_i++)
                            {
                                if(ap_panel.Controls[ap_panel_i] is RadioButtonList)
                                {
                                    RadioButtonList rbl=(RadioButtonList)ap_panel.Controls[ap_panel_i];
                                    al.Add(int.Parse(rbl.SelectedValue));
                                }
                                                
                            }
                        }
                    }
                }
            }2.
 示例：
foreach(Control ctl in this.Controls[1].Controls)
{
if(ctl.GetType().Name=="TextBox")
{
TextBox tb =new TextBox();
tb=(TextBox)this.FindControl(ctl.ID);

Response.Write("<script>alert('" + tb=.Text+ "的值为空。');</script>");

}
}
}
